Which antenna is not wideband?
Electrically small antennas are always narrow-band. The bandwidth of a small antenna has a theoretical maximum defined by the Chu Limit.
What is an ultra wideband antenna?
Antennas can be tuned for specific frequencies to increase their gain. These types of antenna are sometimes referred to as narrowband. An ultra wideband antenna works for a lot of frequencies around what is called a center frequency. For example, if you had a narrowband antenna centered around 10 megahertz it might work for frequencies from 9 to 11 megahertz for example. If it were wide band it might go from 5 to 15 megahertz, and so forth. The bands are clustered around specific center frequencies for different applications.
What is a magnetic conductor?
A magnetic conductor is a material that supports free movement of magnetic charge (magnetic monopoles), similar to an electric conductor that allows free movement of electric charges. On average the net charge is neutral. Of course, magnetic monopoles do not exist, but clever engineering can produce close to the same effects. Importantly, magnetic conductors have hugely different boundary conditions from electric conductors in electromagnetics and physics. A major research breakthrough in demonstration of wideband magnetic conductors was published in 2011 in "Wideband Artificial Magnetic Conductors Loaded With Non-Foster Negative Inductors" by Gregoire, D.J. ; HRL Labs., LLC, Malibu, CA, USA ; White, C.R. ; Colburn, J.S..
What is vhf wideband amplifer?
"wide band amplifiers are those amplifiers which amplify ah a higher band width or in short the frequency range is very wide.. by VHF indicates Very High Freaquency- denotes hiher ranges of freaquency 30MHZ to 300 MHZ these amplifiers are working on these reagions so as we need amplifiers of these range normally the internal capacitace of high freaquency switching will affect the freaquency due to internal juction capacitance(MILLER CAPACITANCE)will attenuate the freaquency so much. to avoid this problem we have to use the high freaquency transistors. normally BFW195 are used for small range of aplications commonly" WITH LOVE MADHAV "MADHAVNAMBIARCK@YMAIL.COM"
Who is Shantanu Padhi?
Dr. Shantanu Kumar Padhi School of Information Technology & Electrical Engineering University of Queensland Biography Shantanu received his Ph.D in Electronic Science (Microwave Engineering) from University of Delhi, India in 1999. His doctoral thesis focussed on novel design of planar antennas for mobile communication system. He held a visiting research appointment with Wireless Research Group (WSG), School of Information Technology and Electrical Engineering (former School of CSEE/ELEC), University of Queensland, Brisbane in 1997. During his stay in Brisbane, he was working on vehicle mounted antennas for mobile communication system. In 1998 he was working as consultant to SB Electromechanicals Pvt. Ltd and Astra Microwave Pvt. Ltd on design development of phased array antenna for radar level gauge instrument. He was also involved on the development of Ku-band ridged horn antenna for satellite and terrestrial communication link. In 1999 he joined Global Positioning System Centre (currently PWTC), School of Electrical and Electronic Engineering, Nanyang Technological University, Singapore, where he was actively involved in the design and development of MEMS antennas and filters for the millimetre-band MEMS RF-Identification Tag (MEMSAT), which was a strategic research project funded by NSTB (currently A*Star), Singapore. During this time he was also involved in other projects; (i) development of RFID system at 2.4 GHz and 5.8 GHz band, (ii) photonic bandgap and (iii) planar antenna array for VSAT applications and (iv) on-wafer RF measurement system upto 110 GHz. The research work results successful lunching of prototypes of RFID system at 2.4 GHz band. In 2002 Shantanu joins Molecular Science division of CSIRO, Melbourne, where he was involved in various projects ; (i) Fractal polymer RFID, (ii) low cost and flexible tag, and (iii) organic electronics. His main research was focussed on covert and overt security features, organic electronics, conducting Polymer, organic diodes, flexible RFID and conducting ink. He joins CSSIP (CRC-SSIP) in 2004 and was working on Microwave imaging of breast cancer project. Currently he is involved in ARC project Target identification with Ultra-wideband Polarimetric Radar. His current research activities includes, design and development of low profile antenna system for UWB communication system, fractal antenna for RFID, time domain near-field and far-field antenna measurements, resonance based target identification, tumor detection and microwave imaging. He has published one book chapter and more than 60 referred articles in journals and conferences. Above retrieved from Answers.com Viper1

Difference between broadband and wideband?
The terms "wideband" and "broadband" mean the same thing. It simply means that a signal or noise or channel has a wide bandwidth. Speed is the simple answer to the difference between broadband internet access and wideband internet access, but it is really more than that. Wideband is a fairly new level of high speed internet access that allows much smoother video streaming and gaming interaction via the internet. TimeWarner has introduced it for residential customers in New York City.
What is a wideband system used for?
A system is wideband when the bandwidth it uses covers a wide range of frequencies. Having a wide range of frequencies available allows one to transmit information on all of them thus allowing great bandwidth.
What is video amplifier?
It is a normal amplifier, fast enough to amplify high frequency video signals. The word "video" means wideband. That's why a video amplifier is used for, for instance, for t.v. signals and in wideband measuring equipment.
What has the author Aminghasem Safarian written?
Aminghasem Safarian has written: 'Silicon-based RF front-ends for ultra wideband radios' -- subject(s): Broadband communication systems, Radio frequency, Ultra-wideband devices, Radio, Receivers and reception
What is wideband amplifier?
A wideband amplifier is an electronic circuit providing constant amplification with a ratio of its low corner frequency to its high corner frequency of more than an octave. The widwband amplifier is complementary in concept to "audio amplifier" (20Hz-20KHz) and "video amplifier" (15KHz to 4.8MHZ). The "opposite" concept is the narrow-band or tuned amplifier. There's a new wideband amplifier technology called PowerBand from TriQuint Semiconductor. end-
What is the Full form of WCDMA in mobile internet protocol?
Wideband Code Division Multiple Access
What is frequency interleaving?
Wideband signal generation systems and methods are provided which employ frequency interleaving for generating wideband signals. A general method increases a digitally synthesized signal's bandwidth by frequency interleaving multiple digitally synthesized signal sources of narrower bandwidth. Frequency interleaving creates a continuous wideband signal by summing multiple narrower band signals that overlap in frequency. According to certain embodiments, digital signal processing (DSP) and analog mixing are used to create the multiple narrower band signals such that a high fidelity, continuous wideband signal is produced when the multiple narrower band signals are summed.
What is the use of video amplifier?
Usually to amplify the video signal across long distances of cable. This is necessary to maintain quality and consistency of the video signal in runs of 100 ft. or more. The word "video" means wideband. A video amplifier is used for any wideband signal.
Why there is network disconnect if songs played?
It's the problem with your wireless broadband/wideband. I have never come across this problem.
